Abstract:
A method and an apparatus of color-space conversion are provided herein. When adjustment of saturation and/or hue is performed on a RGB color signal, pixel luminance will be influenced to some extent. In the conversion method of the present invention, luminance compensation will be performed after global or local adjustment to keep the pixel luminance from being influenced by the color-space conversion. The luminance compensation method is to adjust a compensation value according to a ratio of an adjusted pixel luminance to an original pixel luminance.
